The Collins ProLine 4 avionics suite includes dual autopilots
|
With dual (left and right) flight directors for each autopilot system
|
|
The flight director systems
|
Always default to the left flight director at AP/FD selection
Control the flight director command bars and provide steering signals to the autopilot |
|
Which transponder should be selected if the right flight director is in use
|
#2 independent of which AFCS is selected
|
|
The autopilots are described as
|
Two axis systems with aileron and elevator servos and 2 rudder linear actuators for yaw damping
|
|
The autopilots have trim control for
|
Elevators only
|
|
Each autopilot consists of
|
A pair of flight control computers
Left and right flight directors |
|
The selected AP/FD modes are confirmed by
|
The related indications shown above the attitude sphere on the PFDs
|
|
The flight director commands shown on the PFDs
|
Comes from the master flight director unless TO, GA or APPR modes are selected at which time the indication on each PFD comes from the onside flight director
|
|
A left pointing arrow on the PFDs indicates
|
The left flight director is master
|
|
If the right flight director is master
|
The right flight director provides steering signals to the autopilot: the right HSI is recognized with NAV and APPR modes: ADC 2 provides signals for vertical mode
Transponder 2 should be selected |
|
Failure of the autopilot is indicated by
|
Red Flashing AP indication on each PFD, continous cavalry charge aural alert
|
|
Basic AP/FD modes
|
Roll and Pitch
|
|
Pressing the FD SYNC button on either control wheel while the autopilot is engaged
|
Releases the autopilot servo clutches for manual aircraft control and the green AP and FD arrow annunciations turn yellow
Resets references for FLC, VS, ALT, PITCH and ROLL modes and the FD command bars synchronize with the existing aircraft attitude Yellow SYNC appears on both PFDs if FLC, VS, ALT PTCH or ROLL modes are displayed |
|
An automatic NAV to NAV transfer results in
|
Automatic NAV tuning and course selection for localizer based approaches
|
|
During NAV to NAV transfer, automatic transition from a FMS NAV source to a localizer NAV source and subsequent localizer capture requires:
|
APPR or B/C button be pushed, as appropriate
|
|
During FMS-based approaches, what annunciation must be in view before continuing past the FAF?
|
APPR or GPS APPR, as appropriate
|
|
An amber A annunciation on the PFDs and the AP TRIM LWD caution EICAS message indicates
|
The autopilot is holding continous left wing down via the aileron servo to maintain course or heading or bank angle.
|
|
The TURB button on the flight guidance panel
|
Is an autopilot only mode
Does not change the mode annunciations on the PFDs |
|
The autopilot disengages
|
When both yaw dampers fail(amber YD annunciation on both PFDs and YAW DAMPER caution EICAS message)
|
|
Active or armed status for the AP/FD modes is indicated by
|
Green (active) and white (armed) annunciations
Green/active flashes for 5 seconds on the left, lateral modes and ADC source on the right |
|
Flight mode annunciations shown above the attitude shpere indicate
|
Lateral armed and active modes on the left, vertical armed and active modes on the right
|
|
If the left flight director is in use, the command bars can be removed
|
On both PFDs by pushing the left FD button if the autopilot is not engaged
On the right PFD by pushing the right FD independent of autopilot use |
|
if the button on the side of either thrust lever is pushed while airborne
|
The flight directors provide independant indications (split FDs) and GA/GA mode annunciations appear on both PFDs
The thrust levers advance to takeoff/go-around N1 if autothrottles are engaged The FD command bars indicate 10 degrees noseup/wings level attitude and the autopilot disengages |
|
When the buttons the side of either thrust lever are pused on the ground, the flight director command bars
|
Indicate 14 degrees noseup attitude with both engines running
Reset to 10 degrees noseup if an engine fails Command bank angles up to 5 degrees to maintain the heading existing at rotation if an engine fails. |
|
The altitude set by the ALT knob
|
Is recongnized by the flight director (level off occurs) when the aircraft approaches the altitude while in all vertical modes, except VGP or GS.
